Bones and Skeletal System

Washington, District of Columbia - United States

Many people are familiar with a hambone as a cross-section of a typical bone. The center of the bone is filled with marrow, and this is surrounded by the hardened bone tissue itself. If you would examine a bit of this hard bone tissue under a microscope, it would look like the picture to the right. In bone, the extracellular matrix is composed of collagen with Ca3(PO4)2 deposited in it. Note that since vitamin C is needed for collagen synthesis, getting a little extra while a broken bone is healing would probably be a good idea. Bone tissue is composed of repeating, circular units called Haversian systems. Within each Haversian system, there is a central canal where blood vessels and nerves can be found. This is surrounded by concentric layers of the matrix material called lamellae. The darkly-stained spots are spaces called lacunae which contain the osteocytes.

Skeletal system is the biological system providing support in living organisms. Skin, muscle and bones allow movement. Skin - pliable covering. Muscles do actual moving. Bones give anchor to move against. The skeleton functions not only as the support for the body but also in haematopoiesis, the manufacture of blood cells that takes place in bone marrow. This is why people who have cancer of the bone marrow almost always die. It is also necessary
